COMPOSITION FOR TREATING PICTURES.

SPECIFICATION forming part of Letters Patent N0. 765,577, dated July 19, 1904.

Application filed March 1,1904. Serial No- 196,055. (No specimens.)

To all whom, it may concern.-

Be it known that I, HARRY EDWARD HALL, a citizen of the United States, residing at Mattoon, in the county of Coles and State of Illinois, have invented new and useful Compositions for Treating Pictures, of which the following is a specification.

My compositions consist of the following ingredients, combined in the proportions stated, v1z:

A. Gelatin, four pounds; water, substantially pure, six gallons; carbolic acid, five ounces; leaf-green-color paste, four ounces; equal parts wood-alcohol and oil-cassia thoroughly mixed,two ounces. The gelatin should be dissolved in the water over a slow fire, the carbolic acid (first diluted with water) added very slowly, then the other ingredients added, the whole thoroughly mingled by agitation, and the composition strained While hot.

B. Vegetable castor-oil, five gallons; gasolene, five gallons; oil-Sassafras, five pints; saturated solution of alkanet root, (made by adding three pints of gasolene to two pounds of 'alkanet root and letting it stand twelve hours,

straining before using,) one quart. These ingredients are to be thoroughly mingled by agitation.

In using the above-named compositions the glass to be used is cleaned and laid on a level surface (table) and a sufiicient quantity of composition A (first having been heated by placing bottle containing same in warm water) is applied to the concave surface of the glass to cover the same. The albumen print, having been immersed in Water five or ten minutes for the purpose of softening same, is laid face down on the glass and brought into close contact with same at every point by the use of a rubber roller, the operator being careful to avoid getting the composition A on the back of the print. The back of print is then gently washed with warm water, after which the surplus water is removed with a dry cloth and the print is allowed to dry five minutes. A quantity of composition B is then applied to the back surface of the print and allowed to remain from four to twenty-four hours or longer, if necessary, until the print becomes transparent. The surplus composition B is then removed with a cloth, a slight portion being allowed to remain, and the picture is ready for painting.

By the use of the above compositions the operator is enabled to take his time in doing the work and consult printed instructions before taking each subsequent step. There is no possibility of either of the compositions spoiling or deteriorating with age, thus ruining work which had been begun or finished, and by their use perfect results can be obtained by the novice.

I am aware that gelatin and castor-oil have been used in compositions intended for the same purpose; but I am not aware that all the ingredients of my compositions have been used together.

What I claim, and desire to secure by Letters Patent of the United States, is

1. The herein described compositions of matter, consisting of (A) gelatin, water, carbolic acid, leaf-green-color paste, wood-alcoholand oil-cassia, and (B) vegetable Castor-oil, gasolene, oil-Sassafras, and saturated solution of alkanet root, substantially as described and for the purpose specified.

2. The herein-described compositions of matter for mounting albumen prints on glass and making them transparent so that paints (colors) applied at the back of pictures will show through, consisting of (A) gelatin four pounds, pure water six gallons, carbolic acid five ounces, leaf-green-color paste four ounces, equal parts wood-alcohol and oil-cassia,mixed, two ounces, and (B) vegetable castor-oil five gallons, gasolene five gallons, oil Sassafras five pints, saturated solution of alkanet root one quart, substantially as described.

In testimony whereof I have-signed my name to this specification in the presence of two subscribing witnesses.

HARRY EDWARD HALL.
